POLE OB, POST BASE MOLD.

Application filed October 10, 1921.

To all whom it may concern- Be it known that I, MATT Minosnviorr, acitizen of the United States, residing at Trinidad, in the county of LasAnimas and State of Colorado, have invented new and useful Improvementsin Pole or Post Base hiolds, and of which the following is a specification.

This invention relates to molds for plastic material and has for itsobject the provision of novel collapsible mold adapted for use inmolding the bases or foundations for posts, poles and the like wherebythe post or pole will bc'lirmly anchored in a mass of cement or concreteand be partially protected against'decay by dampness.

i -ln important and more specific object is the provision of a mold forthis purpose which is formed as a sheet consisting of a plurality offlexibly connected slats, the sheet being provided at its ends withnovel fastening means whereby it may be held in cylindrical form whenits use is desired.

Another object is the provision of a de vice of this character which maybe used for casting pole bases in place, or which may be used forcasting cored out blocks for subsequent use.

A further object is the provision of a mold of this character which isprovided internally with a spacing member which operates to hold theassembled form in proper shape and to prevent inward collapsing prior tothe disposition of the plastic material therein.

An additional object is the provision of a mold of this character whichwill be simple and inexpensive in manufacture, easy to use, highlyeliicient in service, durable and a general improvement in the art.

With the above and other objects and ad vantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illus trated in the accompanying drawings, inwhich- Figure 1 is a side elevation of my mold in set-up position.

Figure 2 is a plan view thereof.

Figure 3 is a vertical sectional view taken through the securingmembers.

Figure 4 is a view showing the device collapsed into sheet-like form.

Figure 5 is a vertical sectional view through a base cast about a poleor post.

Serial No. 506,607.

Figure 6 is a vertical sectional view through a cored-out base.

Figure 7 is an elevation of the core.

Referring to the drawings in detail, I have shown my mold as comprisinga sheetlike body of rectangular form consisting of a plurality ofelongated slats 10 which are secured near their ends to a pair offlexible bands 11. the securing means being preferably rivets 0r bolts.It will be seen that these slats 10 may he formed of wood. or metal, aspreferred, and if desired they may be of slightly different widths attheir ends whereby the completed mold, instead of beingpurelycylindrical, may be slightly tapered.

Pivoted at 12, upon one slat and near one edge of the sheet, preferablyupon the slat next to the last one, are swinging latch bars 13 whichhave their free ends connected by a bar 14 which carries a loop-likehandle 15. Extending from these latch bars 13. near the connecting bar141-, are outwardly extending pins 16 which are for a purpose to bedescribed.

Secured upon the other endmost slat a." metal plates 17 which are formedwith up struck tongues 18 beneath which the latch bars 18 areengageable, these tongues being formed at one edge with depressions orrecesses 19 within which may be engaged the pins 16 whereby to preventthe latch bars from subsequently slipping out of engagement with thetongues 18. V

Projecting inwardly from certain of the slats or from all of them. ifpreferred, are projections 20 which may be small nails and which serveas supports for a disk 21 of circular shape which is for the purpose ofholdingthe form in proper position.

The'use of the device is as follows ssuming that a hole has been dug inwhich. it is desired to plant a post or hole, my device is rolled intocylindrical form and the slat bars 13 are engaged beneath the tongues18. The disk 21 is then inserted within the device so that it will seatupon the projections 20 and this disk will serve to expand the rolledform slightly so as to spring the pins 16 into engagement with thenotches or recesses 19 so that displacement of the latch bars will beprevented. The disk may then be removed. A small quantity of concrete orcement is then poured into the mold and the post or pole is placedtherein,

completely the concrete as will be readily apparent.

The dish. 2]. need not be used. it preterrcd.

except to hold the parts in place when the device is not in use so as toprevent injln'y. It will be observed that in use the mold is invertedwith respect to Figure 1 so that the base will be larger at the bottomthan at the top, as shown in Figure 5.

If desired, the mold may be used for easting bases to be subsequentlyplaced in position, in which event I make use of atapered, tin-sheathedcore 222 which. is placed in the mold prior to casting and which issubsequently withdrawn by means of suitable handles 23. This feature isshown in Fig ures 6 and 7.

From the foregoing description and astudy of the drawings it will beapparent that l have thus provided a. simply constructed andconsequently inexpensive mold which is particularly adapted tor use informing the bases or foundations oi posts or poles, the use of my moldresulting; in the provision of a cylindrical anchor or foundation inwhich the postor pole embedded, the cement surrounding the post or poleserving to a great extent to prevent the decay of the latter on accountol'inoisture.

While I have shown and described the preferred embodiment of myinvention, it is of course to be understood that I reserve the right tomake such changes in the form, construction and arrangement of parts aswill not depart from the spirit of the invention or the scope of thesubjoined claims.

What is claimed is 1. A mold of the character described com prising aplurality or flexibly connected p arallel slats, a plurality of flexiblebands se cured to and connecting the slats, the sheet formed by theconnected slats being adapted to be rolled into cylindrical form,spacing means located Within the form and engaging all the slats, andaplurality of latch 1i. rcane? bars pivoted at or near one endniostslut, and offset tongues mounted upon or near the other endmost slat andwith which said bars may engage.

2. A mold of the character described comprising a plurality of flexiblyconnected. parallel slats, a plurality of flexible bands secured to andconecting the slats, the sheet formed by the connected slats beingadapted to be rolled into cylindrical form, spacing means located Withinthe form and engaging all the slats, a plurality of latch bars pivotedat or near one endinost slat, oit'set tongues mounted upon or near theother endmost slat and with which said bars engage, outwardlyextendingpins carried by said latch bars, and the edges oi said tongues beingformed with recesses for the accommodation of said pins.

3. A mold oi the character described comprising a sheet-like memberformed of a plurality of slats flexibly connected together, saidsheet-like member being adapted to be rolled into circular shapeto-define a cylinder, projections extending inwardly from said slats andconstitutinga support, a circular disk seated upon said projections andengaging against the innermost slat, a plurality of latch bars pivotedon a slat one end otthe sheet and connected'for simultaneous movement,and keepers mounted upon a slat at the other end of the sheet andeiigzzurealile by said latch bars.

el. A device of. the character described con'mrising a plurality ofslatsjllexibly connected, a retaining member located within theenclosure formed by the slat and serving to prevent inward collapsing ofthe latter, a, pair of latch bars pivoted upon the slat at one end ot'the series, a crossbar connecting said latch bars for simultaneousmovement and provided with a handle, a pair of metal plates secured uponthe other endmost slat ot the series and formed with upstruck ottsettongues beneath which said latch bars may be engaged, the outer edges ofsaid tongues being formed with recesses, and pins extending upwardlyfrom the latch bars and adapted for engagement with said recesses.

In testimony whereof I ailix my signature.
